Add workqueue-rulecleaner Helm chart

[nhduongvn]

Summary

Adds a new workqueue-rulecleaner Helm chart — a standalone CherryPy pod
running only the InputDataRucioRuleCleaner periodic task alongside the
GlobalWorkQueue service.

The task cleans block-level Rucio replication rules for input datasets of
completed GlobalWorkQueue elements, freeing disk storage once
workflows have finished processing their input data.

Changes

• New Helm chart under helm/workqueue-rulecleaner/ with:
  • deployment.yaml — CherryPy pod mounting workqueue secrets and config
  • configMap.yaml — startup script (setup-certs-and-run.sh)
  • values.yaml — configurable image, resources, and replica count
  • Standard supporting templates (service, ingress, hpa, serviceaccount)

Test

• Deployed and tested on cmsweb-test16
• Pod starts successfully and connects to GlobalWorkQueue CouchDB
• InputDataRucioRuleCleaner runs periodically and cleans Rucio rules for completed elements
• No impact on existing workqueue pod
